[0020] With reference to Fig. 1, preparation method of the present invention comprises the following steps:
[0021] (1) Mix sucrose and drinking water according to the weight ratio of 60-40:40-60, stir evenly, so that the sugar content of the sucrose dilution is 40-60%; (2) the enzymatic hydrolysis reaction uses fructosyl transferase, enzyme The activity is 20-50μ / g. The addition amount is 2 to 10% of the weight of sucrose, the sugar content of the syrup is 40 to 60%, the enzymolysis reaction temperature is 40°C to 60°C, the pH value is 4.0 to 8.0, and the reaction time is 16h to 30h; (3) when fructooligosaccharides account for When the ratio of solids reaches 52-60%, stop enzymolysis; (4) reclaim fructosyltransferase; (5) filter the above mixture with a plate and frame filter press, the initial filtrate should be refluxed, and the filtrate is transported to nanofiltration for purification (6) nanofiltration purification adopts nanofiltration membrane to carry out nanofiltra...
example 1
[0023] 300Kg sucrose and 220Kg drinking water are mixed and dissolved according to the weight ratio, and stirred evenly, so that the concentration of the sucrose dilution is 58% DS (soluble solids); The temperature is 48°C, the pH value is 5.0, and the reaction time is 25 hours; when the proportion of fructooligosaccharides in the solid matter reaches 55%, stop the enzymatic hydrolysis; recover the fructosyltransferase; filter the above mixture with a plate and frame filter press, and the initial filtrate It should be refluxed, and the filtrate should be transported to the nanofiltration purification; the nanofiltration purification adopts the nanofiltration membrane, and when the proportion of fructooligosaccharides in the solid matter reaches 92.5%, stop the nanofiltration; decolorize the syrup; start the vacuum concentrator, when the separation When the vacuum of the device reaches -0.06MPa, open the steam valve. At this time, the working steam pressure is controlled at 0.15...
